Read the introduction and iirst paragraph of an essay about energy sources,
(1) The nation's energy use is largely dependent on fossil fuels. (2) These fuels are nonrenewable resources, and they
cause pollution. (3) We cannot continue our reliance on a fuel that will eventually run out. (4) Thus, we must find other
ways to sustain our energy demands. (5) Pursuing alternative fuel sources is the key to solving our energy crisis.
(6) Currently, about 1 percent of energy in the United States is produced by the sun, and solar energy has the potential
to become a more widely used energy source. (7) Through different technologies, such as solar cells, scientists have
learned to use the sun's radiation to create electricity (8) Solar energy is both inexhaustible and clean. (9) The major
limit to this alternative source is that equipment is expensive. (10) Developing a cost-effective way to harness the power
of the sun will be a significant development in solving our energy crisis.
Which is an alternative piece of evidence that supports the idea that solar energy could play a part in solving the energy crisis?
A) Solar energy is not a suitable solution for all climates due to shorter hours of daylight.
B) Solar power requires a large area for the solar panels, which may be a problem in urban areas.
C) Solar energy already serves an important role in providing electricity to remote areas.
D) With continued support, solar energy will clearly become the energy of the future.
